Wagering requirements explained: what a casino bonus is actually worth
Every welcome offer leads with a big number. Two hundred percent, five hundred free spins, a four-figure package across your first three deposits. The figure that decides what any of it is actually worth is the small one underneath: the wagering requirement.
A EUR 100 bonus with 35x wagering is asking you to place EUR 3,500 in bets before the casino will let you withdraw. That is not a penalty clause buried in the terms. It is the entire economics of the offer, and once you can do the arithmetic in your head you can tell a good bonus from a worthless one in about a minute.
First, check what the multiplier multiplies
There are two conventions, and casinos rarely make it obvious which one they use.
The first applies the multiplier to the bonus alone. Deposit EUR 100, receive EUR 100, wager 35x the bonus, and you owe EUR 3,500 in turnover. The second applies it to deposit plus bonus, usually written as D+B in the terms. Same deposit, same bonus, same 35x, but now the multiplier runs on EUR 200 and you owe EUR 7,000.
Identical headline, double the work. If the terms say D+B, mentally double the wagering number before you compare it to anything else.
The arithmetic that tells you whether to take it
Turnover is not the same as loss. You are not betting EUR 3,500 of your own money; you are cycling a smaller balance through the game many times, and the house takes its edge on each pass.
What it costs you, on average, is turnover multiplied by the house edge. On a slot with a 96 percent return to player, the edge is 4 percent. Clearing EUR 3,500 of turnover therefore has an expected cost of about EUR 140 — to unlock a bonus worth EUR 100.
That gives you a rule you can apply anywhere: multiply the wagering number by the house edge. Below 1, the bonus is mathematically worth taking. Above 1, you are expected to pay more in edge than the bonus hands you.
At 96 percent RTP the break-even point lands at roughly 25x. Anything at 20x is comfortably in your favour; anything at 40x is not, however large the headline. If the house edge is unfamiliar territory, our guide to RTP and house edge covers where that 4 percent comes from.
One honest caveat: this is a comparison tool, not a promise. It tells you which of two offers is better constructed. It cannot tell you what will happen on any given night, because variance dominates over the short run and the terms below can move the number further against you.
Game contribution is the term people miss
Not every bet counts fully. Slots typically contribute 100 percent of the stake toward wagering. Roulette, blackjack and video poker commonly contribute 10 percent, and are sometimes excluded outright.
The effect is larger than it sounds. If a game contributes 10 percent, that EUR 3,500 requirement becomes EUR 35,000 of actual play at the table. This is not an accident of drafting: the games with the lowest house edge are the ones most often restricted, precisely because they would let you clear the requirement cheaply.
The max bet rule is where withdrawals die
Almost every bonus caps your stake while wagering is outstanding — commonly around EUR 5 per spin or hand. Go over it, even once, even accidentally after a session of larger bets on your own money, and the operator can void the bonus and everything won with it.
Of all the ways a withdrawal gets refused, this is the most common and the most avoidable. Set your stake once at the start of a bonus session and leave it alone until the wagering is finished.
Time limits and maximum cashout
Bonuses expire. Seven days is aggressive, thirty is generous, and the window matters more than it looks: EUR 3,500 of turnover in a week is a very different commitment from the same figure across a month.
Then there is the cap on what you can actually take out. No-deposit offers in particular usually limit winnings to a fixed amount or a small multiple of the bonus. A free-spins offer that caps withdrawals at EUR 50 is a trial of the casino, not a payday, and it is worth treating it as exactly that.
Where wager-free and no-deposit offers fit
A wager-free bonus removes the whole calculation. What you win is cash, withdrawable immediately, with no turnover to clear and no max-bet rule to trip over. Measured properly, a modest wager-free offer routinely beats a far larger one carrying 40x terms — which is why we keep a separate list of wager-free bonus casinos.
No-deposit offers are a different instrument again. They cost you nothing, so the expected-value maths above does not really apply; the only questions worth asking are what the winnings cap is and what wagering, if any, applies to them. A no-deposit offer with no wagering attached is the rare case where the answer is simply yes.
The check that takes five minutes
Before accepting any bonus, find these six things in the terms. If the page makes any of them hard to locate, that is itself information about the operator.
- Is the multiplier applied to the bonus alone, or to deposit plus bonus?
- Multiplier times house edge — is it under 1?
- Which games contribute, and at what percentage?
- What is the maximum bet while wagering is outstanding?
- How long do you have?
- Is there a cap on what you can withdraw from bonus winnings?
Operators that publish all six clearly, near the offer rather than four clicks away, tend to be the ones that also pay out without argument. Our casino rankings compare bonus value alongside payout speed and licensing, and the fast payout casinos page covers what happens after the wagering is done — which, once you have cleared a requirement, is the part that suddenly matters most.
